In this paper, we construct combinatorial bases of Feigin–Stoyanovsky’s type subspaces of standard modules for level k affine Lie algebra $$C_\ell ^{(1)}$$ . We prove spanning by using annihilating field $$x_\theta (z)^{k+1}$$ of standard modules

Let be an affine Lie algebra of type and L(Λ) its standard module with a highest weight vector v Λ. For a given ℤ-gradation , we define Feigin–Stoyanovsky's type subspace as By using vertex operator relations for standard modules we reduce the
